Keep your truck cool and running strong with the Dayco Water Pump for 2001–2005 GM 6.6L LB7 and LLY engines.
When you're replacing a worn out original or tackling a full cooling system refresh, this high quality pump is built to handle the heat, literally. Each Dayco water pump is made from 100% brand new castings, the design ensures durability and long term reliability, while the upgraded impeller moves coolant more efficiently to keep your engine at the right temp, even under heavy load. Dayco doesn’t cut corners on internals either. These pumps feature case hardened roller bearings that handle external stress without giving up internal flexibility, so you're protected against bearing failure. Add in premium gaskets and unitized seals to prevent leaks, and you’ve got a water pump that’s built to outlast and outperform.
Meets TS16949 quality standards, so you know you're getting OEM level confidence with aftermarket value. Ready to bolt on and go!

The fit is pretty good, it's acceptable.
Color: Navy Blue, Size: X-Large
Very good fit. The sleeves are long enough, I guess. I'll be rolling them up anyway. I would like it to be a tad bit longer though for tucking in. Other than that it feels nice and lightweight, can't wait to wash it so I can use it for going out.
